乌兰布和沙区渠道灌溉系统受风沙灾害影响十分严重 ,农田灌溉得不到保障 ,防护林的存活和正常生长受到严重制约。渗水管道的应用 ,提高了管道输水效率 ,满足了林木的存活和生长需要 ,增强了渠系抗风沙能力 ,提高了防护林防护效益 ,值得在沙地开发中推广应用
The irrigation system in the channels of Ulan Buh and sandy areas is very seriously affected by the wind-blown sand disasters. Irrigation in farmland can not be guaranteed and the survival and normal growth of the shelter forests are severely restricted. The application of water seepage pipelines has improved the efficiency of pipeline water transportation and has met the needs of survival and growth of forest trees, enhanced the capability of anti-windbreak of canal systems and improved the protection benefit of shelterbelts, which is worth popularizing and applying in the development of sandy land
